全内镜下原发性前交叉韧带重建术联合聚酯合成移植物与股薄肌腱自体移植物：改良的混合4×2股移植物制备技术
简介
本文介绍一种改良的全内前交叉韧带重建技术，采用4×2股混合移植物，即管状合成装置联合股薄肌腱自体移植物。该技术旨在提供更强的移植物以优化稳定性，同时保留骨量并缩短手术时间，尤其适用于职业运动员和高需求患者。文章详细描述了手术步骤、移植物制备、骨道建立及固定方法，但缺乏临床结果验证。
英文摘要
Anterior cruciate ligament reconstruction is a frequently performed procedure in arthroscopic surgery, with rising rates paralleling the incidence of anterior cruciate ligament ruptures worldwide. Synthetic grafts, especially hybrid constructs combining artificial devices with autologous tissue, offer biomechanical advantages and potential faster recovery. This article describes a modified technique for primary all-inside anterior cruciate ligament reconstruction using a 4 × 2-strand hybrid graft composed of a tubular synthetic device combined with the gracilis tendon. This technique aims to deliver a stronger graft, optimizing stability while preserving bone and reducing operative time. The step-by-step surgical method, graft preparation, tunnel creation, and fixation are detailed, with emphasis on biomechanical and clinical benefits for professional athletes and high-demand patients.
